Dungog TP
The Dungog plant currently provides a peak supply capacity of 90 megalitres per day and treats water from Chichester Dam.
Dungog Water Treatment Plant uses a direct filtration method.
Alum and polyelectrolyte are rapidly mixed into the water, causing coagulation and flocculation. The floc is filtered through a filter bed composed of sand, anthracite and gravel, using contact filtration. After filtration water is chlorinated, fluoridated and dosed with lime and carbon dioxide for pH correction and buffering, before being returned to the Chichester Main.
